  producer

  producer refers to

  • (a) in the case of subparagraph 10(1)(b)(i) of these Regulations, the producer of the listed material, and

• (2) Where it is to be determined under subsection 9(3) of these Regulations whether the customs value of a material was determined in a manner consistent with this Schedule for purposes of paragraph 9(2)(c) or (d) of these Regulations, a reference in this Schedule to “producer” shall be read as a reference to “person other than the producer who imports the traced material from outside the territories of the NAFTA countries”.

• 2 (1) Except as provided under subsections (2) and (3), the transaction value of a material under paragraph 7(1)(b) and subsections 9(5) and 10(2) of these Regulations shall be the price actually paid or payable for the material determined in accordance with section 4 and adjusted in accordance with section 5.

• [...]

• (8) A number of factors must be taken into consideration for the purpose of determining whether the transaction value of the identical materials or similar materials closely approximates the transaction value of the material being valued. These factors include the nature of the material, the nature of the industry itself, the season in which the material is sold, and whether the difference in values is commercially significant. Since these factors may vary from case to case, it would be impossible to apply an acceptable standardized difference such as a fixed amount or fixed percentage difference in each case. For an illustration of this, a small difference in value in a case involving one type of material could be unacceptable, while a large difference in a case involving another type of material might be acceptable for the purposes of determining whether the transaction value closely approximates a test value set out in subsection (4).

[...]

• 5 (1) In determining the transaction value of the material, the following shall be added to the price actually paid or payable:

  • [...]

  • (b) the value, reasonably allocated in accordance with subsection (12), of the following elements where they are supplied directly or indirectly to the seller by the producer free of charge or at reduced cost for use in connection with the production and sale of the material, to the extent that the value is not included in the price actually paid or payable:

    • [...]

    • (iii) an indirect material, other than those referred to in subparagraph (ii) or in paragraphs (c), (e) or (f) of the definition indirect material set out in subsection 2(1) of these Regulations, used in the production of the material being valued, and

• [...]

• (12) The producer shall choose the method of allocating to the material the value of the elements referred to in subparagraphs (1)(b)(ii) through (iv), provided that the value is reasonably allocated to the material in a manner appropriate to the circumstances. The methods the producer may choose to allocate the value include allocating the value over the number of units produced up to the time of the first shipment or allocating the value over the entire anticipated production where contracts or firm commitments exist for that production. For an illustration of this, a producer provides the seller with a mould to be used in the production of the material and contracts with the seller to buy 10,000 units of that material. By the time the first shipment of 1,000 units arrives, the seller has already produced 4,000 units. In these circumstances, the producer may choose to allocate the value of the mould over 4,000 units or 10,000 units but shall not choose to allocate the value of the elements to the first shipment of 1,000 units. The producer may choose to allocate the entire value of the elements to a single shipment of material only where that single shipment comprises all of the units of the material acquired by the producer under the contract or commitment for that number of units of the material between the seller and the producer.

• 6 (1) If there is no transaction value under subsection 2(2) or the transaction value is unacceptable under subsection 2(3), the value of the material, referred to in subparagraph 7(1)(b)(ii) of Part IV of these Regulations, shall be the transaction value of identical materials sold, at or about the same time as the material being valued was shipped to the producer, to a buyer located in the same country as the producer.

• 7 (1) If there is no transaction value under subsection 2(2) or the transaction value is unacceptable under section 2(3), and the value of the material cannot be determined under section 6, the value of the material, referred to in subparagraph 7(1)(b)(ii) of Part IV of these Regulations, shall be the transaction value of similar materials sold, at or about the same time as the material being valued was shipped to the producer, to a buyer located in the same country as the producer.

8 If there is no transaction value under subsection 2(2) or the transaction value is unacceptable under subsection 2(3), and the value of the material cannot be determined under section 6 or 7, the value of the material, referred to in subparagraph 7(1)(b)(ii) of Part IV of these Regulations, shall be determined under section 9 or, when the value cannot be determined under that section, under section 10 except that, at the request of the producer, the order of application of sections 9 and 10 shall be reversed.

• 9 (1) Under this section, if identical materials or similar materials are sold in the territory of the NAFTA country in which the producer is located, in the same condition as the material was in when received by the producer, the value of the material, referred to in subparagraph 7(1)(b)(ii) of Part IV of these Regulations, shall be based on the unit price at which those identical materials or similar materials are sold, in the greatest aggregate quantity by the producer or, where the producer does not sell those identical materials or similar materials, by a person at the same trade level as the producer, at or about the same time as the material being valued is received by the producer, to persons located in that territory who are not related to the seller, subject to deductions for the following:

  [...]

• 10 (1) Under this section, the value of a material, referred to in subparagraph 7(1)(b)(ii) of Part IV of these Regulations, shall be the sum of

• 11 (1) Where there is no transaction value under subsection 2(2) or the transaction value is unacceptable under subsection 2(3), and the value of the material cannot be determined under sections 6 through 10, the value of the material, referred to in subparagraph 7(1)(b)(ii) of Part IV of these Regulations, shall be determined under this section using reasonable means consistent with the principles and general provisions of this Schedule and on the basis of data available in the country in which the producer is located.
